Phantom, I agree the landowners names have never been that important to me either. But for the minor, additional cost, my thought is why not.
On second thought, same year in Wyoming, we had access to a private ranch in Unit 7 for elk. 2 sides were other private property, one relatives with the same last name. The maps option kept us on the right ranch.
Plus, someday I might be inclined to call a landowner, or know their name before I approach them. Doubt I'd ever ask for permission to fill my tag but some people may be more sympathetic to allow a woman or kid to hunt their property.
